Zest the orange and sprinkle the zest onto wax paper or parchment paper. Cover loosely with a paper towel. Let sit at room temperature until the zest is completely dry (about 1 day).
Grind the orange zest in a mortar with a pestle into a coarse powder. (You should get about 1 teaspoon dried ground orange zest.)
Add ground orange zest along with all remaining ingredients to a bowl and stir until well combined.
Store in an airtight container in a dark, cool place.

How to use it: This orange pepper seasoning is great on boneless, skinless chicken breast, chicken thighs or any other cut of chicken. Rub the seasoning on the meat, then grill or broil.
